Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed June 13. 1906. Serial No. 321.481.

To all whom it may concern:

Be it known that I, JAMEs Pnnsron MAUZEY, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented new and useful Improvements in VVater-Heaters, of which the following is a specification.

The invention relates to an improvement in water heaters designed primarily for use in connection with a water circulating system and constructed to water.

The main object of the present invention is the production of a water heater which may be removably connected to an outlet of a water circulating system, whereby to heat the water flowing from the outlet to any desired degree, the device being of a portable character to permit its ready and convenient use in connection with bath tubs, sinks or the likev The preferred details of construction of the present invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in elevation partly in section, illustrating, the use of my improved water heater in connection with a bathtub, Fig. 2 is a vertical central section of the heater, Fig. 3 is a top plan view of the heater, Fig. 4 is a section on line 44 of Fig. 2, Fig' 5 is a detail section illustrating the connection between the fire casing and the cover taken on the line 5-5 of Fig. 3.

Referring particularly to the drawings, my.

improved water heater comprises a tank 1, open at top, and provided near the bottom with an opening 2, with which communicates a pipe section 3, preferably secured to the wall of the tank and arranged at the upper end for the reception of one end of a flexible tube 4, the opposite end of which is designed for connection with a faucet or other outlet 5 from the water system. Diametrically' opposite the inlet 2, and near the upper edge the tank is formed with an outlet 6, which communicates with a rectangular receptacle 7, in open communication near the lower end with a short outlet pip 8. The tank is closed through the medium of a cover 9, preferably a single sheet of material circumferentially bent at the periphery to provide a bead 10 and a depending flange 11, so that the flange fits snugly within the tank, with readily heat the the bead l0 resting upon the free edge of the tank. Two or more screw bolts 12 pass through the wall of the tank and extended parts of the flange of the cover, equal distances apart, whereby to removably secure the parts in relative position and hold the heater compactly together.

13 represents what I term a fire casing or pot, bein designed to contain a heating agent. T e casing 18 is secured directly to the cover 9 through the medium of a connection to be later described, said casing beingof less diametrical extent than the cover so as to provide an annular space between the wall of the tank and the wall of the fire pot when the latter is in place. The

wall of the casing depends from the cover at right angles thereto for a distance to provide a cylindrical body 14, the lower portion or bottom of the casing beyond the ed e of the portion 14 being of frustoconicals ape, as at 15. The casing is secured to the cover through the medium of a connecting strip 16 Which is secured at its lower edge to the wall of the casing on the inner side of the same, and projects from said wall at an upward and inward incline, terminating in alinement with the upper edge of the casing. At this point the connecting plate is bent laterally toward the casing wall and downwardly into contact therewith, the laterally-projecting portion of the connecting plate providing a ledge in alinement with the u g per free edge of the casing, upon which t e cover 9 is adapted to rest, and to which it is secured through the medium of screw bolts 17, all as clearly shown in Fig. 5. The casing is of less height than the tank, it being preferably so provided to afiord a space therebeneath for the circulation of water.

The cover 9 within the plane of the casing is provided with a centrally arranged elliptical shaped draft and feed opening 19, in which is suspended an elliptical and draft. funnel shaped tube 20, the lower end of which terminates some distance above the bottom of the casing, while the upper end is provided with a removable cover 21. To one side of the central feed and draft 20 the cover is formed with another draft opening 22, preferably of crescent shape and receiving a tapering shaped draft pipe 23, the upper end of which is preferably closed by a cover member formed in sections 24 and 25 and arranged to permit either or both sections to be disposed above the draft pipe or to be moved laterally therefrom to afford the necessary draft to the flue within the casing.

Beyond the feed and draft opening 19 in the direction opposite to the crescent draft openin is arranged an escape opening 26 with w ich opening is connected the smoke pipe 27, which is intended to be sufficient in length to reach any desired outlet. By preference the upper edges of the draft tubes 20 and the draft tubes 23 are bent laterally to provide flanges which rest upon the cover adjacent the respective openings, whereby to separate said parts in a manner to permit ready removal.

Spacing blocks 28 are arranged at equal distances apart about the interior of the tank, being preferably of a cylindrical nature and held between flanges 29 projecting from the wall of the tank. The blocks are of a size to maintainthe fire casing in relatively fixed spaced relation with the wall of the tank, it being understood that said blocks are so disposed as to bear against the portion 14 of the casing. The tank is also provided with a drain outlet 30 sealed by a suitable closure, whereby to empty the tank of the contained water when desired.

The portable character of the device and its construction'provides for many varied uses of the heater.

The parts described are preferably of sheet metal, the cover being usually of cast iron, though the use of other serviceable material is contemplated.

Having thus described the invention what is claimed as new, is

1. A'water heater comprising a tank having an inlet and an outlet, a cover removably secured on the tank, and a fire pot removably connected to the cover and depending within the tank, said fire pot having a cylindrical Wall extending at the upper end in parallel relation to the wall of the tank and inclined inwardly relative to the tank wall at the lower portion, and spacing blocks carried by the tank and bearing against the arallel portion of the vertical Wall of the life pot.

2. A water heater comprising a tank having an inlet and an outlet, a cover removably secured to the tank, a fire ot adapted for insertion within the tank, a p urality of brackets secured to the inner surface of the fire pot wall, said brackets'having Qrtions projecting at right angles to the p ane of the Wall, and means for securing the cover to said projected portions of the brackets.

3. A water heater com rising a casing having'an inlet and an out et, a receptacle in open communication with the outlet, a cover for the tank, a fire (pot com rising a cylindrical wall extende in para lel relation to the Wall of the tank for a'portion of the length of said fire pot and inclined inwardly relative to the tank wall for the remainder of its length, brackets secured to the inner surface of the fire pot wall and having an upper extended portion in alinementwith the upper edge of the fire pot wall, means for removably securing the cover to said extended portion of the brackets, the free edge of the cover being formed with a downwardly projecting flange adapted to snugly fit Within the wall of the casing, means for removably securing the cover to said casing wall, a feed pipe supported by the cover and de ending within the fire pot, the lower end 0 said feed pipe projecting below the u per edge of the inclined portion of the Wal of the fire pot, and a draft tube carried by the cover and depending within the fire pot, said draft tube terminating at the lower end above the lower end of the feed pipe.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES PRESTON MAUZEY.
